| Accepted Name |
|---|
| Tetrachloroethene reductive dehalogenase.
|
| Alternative Name(s) |
|---|
| Tetrachloroethene reductase. |
| Reaction catalysed |
|---|
| Trichloroethene + chloride + acceptor <=> tetrachloroethene + reduced acceptor |
| Cofactor(s) |
|---|
| Iron-sulfur.
|
| Comment(s) |
|---|
- This enzyme allows the common pollutant tetrachloroethene to support
bacterial growth and is responsible for disposal of a number of
chlorinated hydrocarbons by this organism.
- The reaction occurs in the reverse direction.
- The enzyme also reduces trichloroethene to dichloroethene.
- Although the physiological reductant is unknown, the supply of
reductant in some organisms is via reduced menaquinone, itself formed
from molecular hydrogen, via EC 1.12.5.1.
- Methylviologen can act as electron donor.
- Formerly EC 1.97.1.8.
